This is apparently used for fallback selection and if available it is "assumed"
Shadow DOM is also available, while this is a utility function.
Webcompat is a nightmare sometimes.
At first, HTMLEditor::GetActiveEditingHost might return null in this situation, we should check whether nullptr is returned. At second, SplitNodeDeep returns error since curent is design mode and selection node has no parent. So we should check error.

Aspect Ratio handling simplified by using floating point integers:
- Multiplication of value (or inverse value) to a known side for Scaling
- No unequal equal values such as "4/3" vs "8/6" vs "20/15"
- Truly "Empty" aspect ratios, even if one dimension is not 0
I meant to do this a long time ago, but basically it accounts for the new XP_SOLARIS build flag that never made it into the MailNews code. Additionally, it enables a compatibility flag for Solaris 11.4 that allows us to use the three-argument implementation of ctime_r still used by Solaris 11.3 and illumos (which also appears equivalent to the NSLDAPI_CTIME implementation used by libldap internally). Also, the ctime_r function has been added to the time.h header library for a while now, not sure why Mozilla thought we didn't have a ctime_r implementation.
When using AF_CONN addresses, don't put these in the COOKIE
chunk. For these addresses it is possible to reconstruct them
locally. Conceptually, addresses are something to be shared
with the peer, but in the case of AF_CONN this might not be
the case. Therefore, zero then out.
Thanks to Natalie Silvanovich of Google Project Zero for
finding and reporting the issue.
JIT optimizations involving the Javascript 'arguments' object could
potentially confuse later optimizations, so we simply disable these
optimizations as a DiD measure.
These should all be spec-compliant and were (for release-trickling of features)
arbitrarily disabled by Mozilla at our fork point. There's no real reason to
keep them disabled since they are used in the wild.
A version bump triggering add-on compatibility check will re-evaluate the "native" status (among other things) so no extra or special work is required to fix erroneous warnings.
tl;dr instafix!
The added debug assertion did not take into account microtask refactoring done in BZ 1405821.
Resulting in error: no member named 'IsInMicroTask' in 'nsContentUtils'.
This resolves the error.
Looks like this was just lazily lumped in with WebExtension stuff and got
removed as a result. This should prevent the autorefresh blocker from leaking.
This changes NativeObject::slotSpan() to get the class from the object group
rather than getting it from the base shape to avoid a race between
Shape::ensureOwnBaseShape and background sweeping.
